Crate scribble 

scribble — a small, focused transcription library with a pluggable ASR backend.

Overview

Scribble provides a clean, idiomatic Rust API for audio transcription, designed to work equally well in CLI tools and long-running services.

At a high level, Scribble wires together:

• Media demuxing and audio decoding (via Symphonia)
• Audio normalization and resampling (mono, 16 kHz)
• Backend inference (built-in Whisper backend available)
• Pluggable output encoders (JSON, VTT, etc.)

The library emphasizes:

• Explicit control flow
• Streaming-friendly design
• Clear separation of concerns
• Minimal surprises for callers

Most consumers should start with crate::Scribble.
